This is a fuel sending unit for the CJ3B and early CJ5 with the under seat gas tank. The year range is 1955-1972. This can be used with both the 6 and 12 volt systems. Sorry, I don’t know the ohms. These will fit right in the original as well as the reproduction gas tanks. This sending unit has six mounting holes. This comes with the correct gasket.
Part number 914850
